@briankrebs I figure someone will point out the existence of tools like twitodon or movetodon, either as a counter-example, or a way to address the tradeoff of making the connection process more convenient, as a service to the user. And so, I want to point out, having a way to find them is fundamentally different from exposing them, and if you wanted a good and trustworthy tool to expose selected rows and columns of your addressbook, it's easier to just bcc them, and/or post to whatever group.
